The most common reason we hear is that the PS3 has been dropped or knocked while plugged in. This causes the HDMI cable to yank out and physically damage the port. It can also happen while plugging in the cable. The ports are quite delicate so if the HDMI cable isn’t plugged in carefully to the PS3 it can cause damage.
There are other faults that can cause the HDMI output not to work too. If the port looks physically fine and isnt wiggling around, it coul dbe the contolling IC chip on the motherboard. We can swap this too but sometimes it can be a general hardware fault on the motherboard.
If the consolse doesn’t output on AV and you have tried the AV reset and it still doesn’t work, it could be a problem with the GPU. The same fault that causes YLOD can cause the PS3 to have no output too. This would cause the output to fail on all connections.
How do we repair the PS3?
To repair this fault we need to carefully strip the console down to the motherboard. From there we desolder the old HDMI port. The port is attached by many pins that are through hole soldered. Once the old port is removed the solder pads of the logic board are inspected for damage. If the original port is really badly yanked this can cause damage to the motherboard and in some circumstances could be beyond repair (although that is very rarely the case).
Once we have cleaned up the board and prepped the solder pads for the new port we solder the new HDMI port to the PS3. We reassmeble the console and it goes down to our testing bench where all consoles are tested for at least 4 hours.
